==Non-linear measures of correlation==

I have been working on how to quantify the reciprocal interaction of time-series over time. I am using Recurrence Plots (http://www.recurrence-plot.tk/glance.php). If anybody is interested in discussing this method, I am willing to prepare a small tutorial on what recurrence plots are and how I have been using them.

==Order Book Dynamics: Learn how to trade in 15min==

--I'm happy to repeat this -just get in touch with me.--

If you are curious about how stocks trade and want to try your luck, I'll
be going over some of the basics with a hands-on example.

Meet at 7.30pm in main lecture hall Thursday June 7th. Please make sure
to bring your laptop.

Sanith

==Update==

Hi guys

I guess the main lecture hall is free at 6.30 pm and so we can meet there. I have a small talk through the idea and then maybe we can try out getting bifurcation plots for one or two systems. I use software written in MATLAB for the demo but the idea can be implemented in any software.

Here's a link to the [[software for numerical continuation|http://twr.cs.kuleuven.be//research/software/delay/notice.shtml]]. This software can handle systems with time delays and can be used to obtain the bifurcation behaviour.

(1) Please download the software DDE-BIFTOOL and unzip.

(2) Within the folder, you will find another zipped folder in small case ‘ddebiftool’. Please unzip this into a folder with the same name

(3) Add the location of the folder to the path of MATLAB.
I have also sent out a mail with a zipped folder containing files to get a bifurcation plot for a Rijke tube system.
Do let me know if anyone did not get this.
See you there!

Priya

==An easier way to get a bifurcation plot==

Hey guys
I have been working in the past in obtaining bifurcation plots for different physical systems. There's a better way to get these pictures instead of getting the evolution at every parameter value of interest. This is called ''numerical continuation'' and basically involves tracking a curve. I plan to give a informal talk on how to do this and maybe even a demo on applying this technique on 14th June at 6.30 pm. Do mail me if you are interested at '''iitm.priya@gmail.com''' or sign up below.

==Using Tisean on R on OS X==
first install TISEAN, like you've done already. Make sure R is up to date (v 2.15).
you can try to install RTisean from CRAN
install.packages("RTisean"); library(RTisean); henon()
But me and Dave both got an error about some bad file name, something about con and something about a long path involving -Tmp-
Solution:
remove.packages("RTisean")
restart R
download this: http://cl.ly/0I0b2P2L311y1q0q0y0n
install it, it changes line 74 of nativeTISEAN.R which has some problems with file handling
If you are golden, then:

==A conceptual shell==

One thing that I think has been missing from this course is an explicit set of concepts and tools which we can use to relate all of the talks we've been listening to. Last fall, two other graduates students and I taught a survey course on complexity. We put together the following document, which contains one-paragraph summaries of what we felt were the 20 most important concepts that comprised the field of complexity. These were the "glue" that we used to relate all of our lectures and workshops. Most of these will probably be familiar to you, but I think they serve as a nice, concise reference and may be helpful in tying all of this information overload together. One caveat: These are works in progress and are in alphabetical rather than any logical conceptual order.

''Please post your questions or additional comments on this page. This Friday this session of the Glue Session will be held as a forum, please post your questions below.''

*What are the limits of the methods (analysis, simulation, experiment, meta-analysis, ethnography) you use for the questions you are interested in?
*What methods would you be excited to see supplement and complement your approach?

* If emergence is not reducible to the property of the parts then where does it 'emerge' from?

* If fundamental law is derived from symmetry relationships, then what is the 'law' that drives the process of 'symmetry-breaking'?

* What systems are clearly not 'complex'?

* What are the principles and mechanisms that lead to the emergence of robustness in biological systems?

* Among the different measures of complexity, does the value for one measure of complexity give any information about the others or are they completely unrelated?

* Regarding the tools and mathematical formalisms we use to model complex systems, does the fact that they apply to so many diverse types of systems (e.g., disease, culture, ecology) tell us anything deep about the structure of these systems, or about the mechanisms underlying them, or are these tools nothing more than simply very flexible and useful tools?

* Knowledge is growing at a tremendous rate, which is reflected in an inflation of education. Nevertheless, our learning methods do not improve at the same rate. Which are or will be new more efficient ways to learn as students and in research driven academia?

If you are curious about how stocks trade and want to try your luck, I'll
be going over some of the basics with a hands-on example.

Meet at 7.30pm in main lecture hall Thursday June 7th. Please make sure
to bring your laptop.

==Update==

Hi guys

I guess the mail lecture hall is free at 6.30 pm and so we can meet there. I have a small talk through the idea and then maybe we can try out getting bifurcation plots for one or two systems. I use software written in MATLAB for the demo but the idea can be implemented in any software.

Here's a link to the [[software for numerical continuation|http://twr.cs.kuleuven.be//research/software/delay/notice.shtml]]. This software can handle systems with time delays and can be used to obtain the bifurcation behaviour.

(1) Please download the software DDE-BIFTOOL and unzip.

(2) Within the folder, you will find another zipped folder in small case ‘ddebiftool’. Please unzip this into a folder with the same name

(3) Add the location of the folder to the path of MATLAB.
I have also sent out a mail with a zipped folder containing files to get a bifurcation plot for a Rijke tube system.
Do let me know if anyone did not get this.
See you there!

Priya

==An easier way to get a bifurcation plot==

Hey guys
I have been working in the past in obtaining bifurcation plots for different physical systems. There's a better way to get these pictures instead of getting the evolution at every parameter value of interest. This is called ''numerical continuation'' and basically involves tracking a curve. I plan to give a informal talk on how to do this and maybe even a demo on applying this technique on 14th June at 6.30 pm. Do mail me if you are interested at '''iitm.priya@gmail.com''' or sign up below.

==Using Tisean on R on OS X==
first install TISEAN, like you've done already. Make sure R is up to date (v 2.15).
you can try to install RTisean from CRAN
install.packages("RTisean"); library(RTisean); henon()
But me and Dave both got an error about some bad file name, something about con and something about a long path involving -Tmp-
Solution:
remove.packages("RTisean")
restart R
download this: http://cl.ly/0I0b2P2L311y1q0q0y0n
install it, it changes line 74 of nativeTISEAN.R which has some problems with file handling

The spectrum of my scientific interests is wide-- which makes me an expert at nothing. I find much pleasure in exploring and sharing ideas about subjects such as adaptive networks, evolutionary theory, diseases (transmissible or not), human evolution and behavior, among others. This summer school, I excitedly suspect, will be a wonderful environment to engage in fruitful discussions of this kind.

I am originally from Cuba, where I did my undergraduate studies in Physics. Still passionate about Physics in general, I decided to switch gears and look into Applied Mathematics. I am in the second year of my Ph.D. at Arizona State University.

==Project Interests==
My research is basically related to mathematical epidemiology. More specifically, I am currently interested in the interplay between the evolution of transmissible diseases and population's contact structures. That is, how disease traits, such as virulence, evolve in response to the topological properties of the social network, and how, in turn, the disease dynamics influences the adaptive behaviors of the agents/nodes in the network and hence its topology. This, in a sense, is a broad research question, thus it can be framed or contextualized in many ways; ways that I am more than happy to talk about, explore and expand during my time at this CSSS. Finding answers to questions of this kind could be relevant to major public health issues such as the evolution of microbial drug resistance, the emergence of new diseases and vaccine designs.

That said, I am always susceptible to being infected with new exciting ideas.
